Seating Long Until Ready for Use

[Rosebud]

Dry graphite lube for neck sizing. I use a bushing die for bump neck sizing. Once done I push the case neck into the graphite tub six or eight times, then load. After that I use a LFC die. So far no cold weld. But I've had it in the past when loading Berger bullets into new brass. Someone else told me about the graphite.

Jeff, as someone that knows virtually zero about "cold welding"…..I'll make a comment anyway.

I don't think that it's so much about accuracy or anything other than "potential" over pressure!

For so of us that may "push the envelope" on pressures…..a "significant" cold weld could very easily push us into a dangerous pressure level! Just my take on cold weld problems!

So……if someone loads in bulk, expecting the ammo to be used years down the road…….."long seating" will prevent a problem that may very well have never happened! Simply……..cheap insurance! memtb

Have not read the entire thread however, my builder and friend is a HOF BR shooter who has held world accuracy records. He is adamant about this and loads at the range during the match when he competed at 100yds. When working up a load for a new tube or a new rifle always seat the bullets the day before I shoot. This ensures a "fresh set" into the neck. When loading for a 1k BR match loading ammo is the last thing I do before going to bed the night before.

The concept....is good, but why would a person be foolish enough to load 400 Rds at a time ....if worried about Cold Weld. Too many variables for me to risk 400 Rds at once. Just me!

I have a couple hundred loaded for every chambering I load with a bunch of 5.56 and pistol rounds too. I've only gotten into cold weld a couple times over 20 years, even though I usually keep better than 5K rounds loaded total.

skipglo……some of us consider 500 rounds near nutt'n. Whe the "ship hits the sand"……cold weld will be the least of our problems! memtb
